Olympians Cate Campbell and Bronte Campbell at the Nuromol stand during the 2016 Pharmacy Assistant National Conference. Client: Reckitt Benckiser.

I recently had the pleasure of photographing two of Australia's medallists at the Rio 2016 Olympics, Brisbane's Campbell sisters - Cate and Bronte.

The swimmers were guest speakers at the Pharmacy Assistant National Conference at Sea World Resort on the Gold Coast about six weeks ago, representing the new double-action pain relief medication Nuromol. The tablets contain both ibuprofen and paracetamol and have the marketing slogan "The Power of Two".

I was commissioned by agency CHE Proximity to photograph the sisters at the Nuromol stand and during their speaker session, when the sisters talked of their journey and the importance of each other in their respective sporting successes, for parent company Reckitt Benckiser.

The sisters each won bronze in the Women's 4 x 100m Freestyle Relay at Rio, while Cate also won silver in the Women's 4 x 100m Medley Relay.
